Feb. 7, 2019 (Phys.org) -- Religion can be a mixed blessing for children as they get older, research shows.

Third-graders' psychological adjustment and social competence were positively correlated with various religious factors. However, students' performance on reading, math, and science tests were negatively associated with several forms of parental religiosity.

Researchers analyzed data from the Early Childhood Longitudinal Study (ECLS)-Kindergarten Cohort to complete the study. They examined the effects of parents' religious attendance and how the religious environment in the household (frequency of parent-child religious discussions and spousal conflicts over religion) influenced a nationally representative sample of third-graders.
